WHIVFFLET'REE.

SPECIFICATION forming part of Letters Patent No. 369,625, datedSeptember 6, 1857.

Application led July 18, 1887. Serial No. 244,621. (No model.)

T0 all whom it may concern,.-

Be it known that I, JOHN H. WooDARD, a citizen of the United States,residing at the city of Lapeer, in the county of Lapeer and State ofMichigan, have invented certain new and useful ImprovementsinWhifletrees; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as Will enable othersskilled in the art to which it appertains to make and use the saine.

Figure lis a perspective view of the present device. Fig. 2 is a. detailin perspective of one end of the device shown in Fig. l. Fig. 3 is adetail in perspective showing the end in process of construction-thatis, before the slit parts of the knuckle are hammered down; Figs. Lland5, details in section of the knuckle and the screw-threaded end of thebody of the device. i

This invention relates to that class of devices kn'own as singletrees orwhifletrees5 and the points oi' novelty consist in the eonstruction ofthe several parts and in their combination as a whole, all as will nowbe more fully set out and explained, reference being had to theaccompanying drawings.

In the drawings, A denotes the body of this device, which is made ofgaspipe, each end of which is screw-threaded at ct. Upon each of thesescrewthreaded ends is placed the metal knuckle B, which is internallyscrew-threaded to adapt it to iit upon the end of the body A. The outerend of each knuckle has a slit, b, and into these slits the ends ofthemetal yoke C are fitted in any suitable way after the knuckles have beenscrewed upon the body A; and in order to retain the end of the yokesecurely within these slits, and to make a good finish at this point,the sides b of the slits are hammered down over the end of the yoke C,just above the eye cof the yoke. ln this eye are placed the usual hooks,D. The yoke C is bent centrally, so as to provide at c an eye to attachthe singletree to the carriage or vehicle. Preferably the sides of theyoke incline from c' toward the ends ofthe body; but this is notabsolutely necessary.

It will be obvious that many changes in the mere mechanical details ofthe structure ol' this device can be made Without departing in anyessential degree from the nature and scope of the inventionrasillustrated and as above described.

Having now described this invention, what I consider new, and desire tosecure by Letters Patent, is-

1. A singletree consisting of arnet-al body, A, having knuckles B,internally screwthreaded and slit at their outer ends, attached to eachend and combined with the yoke C, substantially in the manner and forthe purpose set forth.

2. As a new article of manufacture, a singletree consisting of thegas-pipe body A, having metal knuckles B, slit at their ends and.securedupon the ends of the part A and combined with the yoke C, havingeyes c and c', the slit ends of the knuckle being hammered over theouter ends of the yoke C.

l In testimony whereof I affix my signaturein presence of two witnesses.
